f350, 6.7
I've heard that the 6.7 is a very good engine. I've also heard that this engine first appeared in pickups in 2012. And that there were some issues with that engine up until 2016. And since then, all t...

This is why I recommended 2015 and newer:
2015 Model Year Changes:
The 6.7L Power Stroke underwent significant revisions for the 2015 model year, most of which contributed to or supported the increase in output from 400 hp/800 lb-ft to a maximum 440 hp/860 lb-ft.
• Particulate matter sensor and sensor module added at the DPF outlet in order to measure filtration effectiveness.
• Fuel pressure and fuel temperature sensors for low pressure fuel system combined into a single sensor, no longer two individual sensors.
• EGR cooler flow redesigned, now using the high temperature cooling system (same circuit as the engine) instead of the low temperature system (which still provides cooling for the charge-air-cooler, fuel system and transmission cooler).
• EGR inlet temperature sensor added.
• Revised fan clutch design with additional heat sinks in order to more effectively dissipate heat, thereby improving durability.
• IROX polymer coated lower main bearings introduced for added durability at greater performance levels.
• Larger GT37 single variable geometry turbocharger replaces the GT32 twin compressor "DualBoost" turbo. Improved throttle response and high altitude performance. Wastegate eliminated, turbocharger produces ~30 psi at max load with an impeller speed of ~130,000 rpm.
• New lower intake, required to match new turbocharger.
• Manually activated, more effective exhaust braking system added, works in conjunction with new VGT.
• Upgraded high pressure fuel pump (injection pump). New pump looks identical, but features a longer stroke.
• Revised injector design, more efficiency nozzle design for reduced emissions and improved performance.
• Larger crankshaft damper with more mass.
• Strengthened cylinder head design.
• High capacity torque converter introduced, transmission shift schedule not significantly altered.
